Work Material [Precipitation Hardening Stainless Steel]
Key Point on Machining
During high performance drilling of 15-5PH precipitation hardening stainless steel, abnormal
damage such as chipping and fracturing of the cutting edge occurs easily because of the high
strength of the material. The MMS drill series enables stable machining due to an excellent
coating in combination with an optimized tool geometry.
Application Example
Extended use is possible because there was only a small amount of wear after machining
400 holes. (Benchmark target was 200 holes)
